Easy to use:You can adjust the voltage by placing a multi-meter on the output, at the same time using a precision screwdriver to adjust the potentiometer. It can be minute adjustments to achieve a precise voltage(clockwise buck , counterclockwise boost).

Package Include:5 xMP1584EN DC-DC adjustable buck converter.
Attention:
1.Do not reverse the positive and negative terminals to avoid any possible damage.
2.Do not use light load (less than 10% of output power) or without load,put at least a 300mA load on it, no less.
3.The input voltage must be higher (at least 3V) than output,No boost!
4.The Diameter of through holes is 0.047", so it doesn't fit in a breadboard.
5.There is only a single input with two holes for each positive and negative,but it is not two separate inputs.
